I 6 Claims. (01. 177-353) The present invention relates to telegraph signaling apparatus and more particularly to selecting mechanisms adapted especially to stock quotation .systems.

The present application is a division of copending application Serial No. 58,340, filed January 9 1936, Patent No. 2,147,656, dated Feb. 21, 1939, and reference may be had thereto for a more complete understanding of transmitting 19 and receiving systems wherein signals especially adapted to the supervision and operation of mechanisms of the present invention are employed.

The principal object of the present invention is the provision of a unitary structure embodying the features of compactness, interchangeability of component selectable elements, and adaptability to structural enlargement to accommodate a comparatively large number of selec- 20 tive possibilities.

The disclosed embodiment features a supporting base which may be of variable length to accommodate a predetermined quantity of parallelly disposed sub-units. A motor driven main operating shaft carries several power distributing elements and a number of selector bars are parallelly disposed corresponding to the sum total of all of the selecting impulses which relate to several conventional start-stop signals. A

corresponding nurr 2r of magnets which may be energized by a suitable distributor impart a mechanical setting to alike number of principal,

storage elements. From these, the setting is communicated to parallelly arranged connector bars by means of a group of transfer levers which are simultaneously reciprocate'd by a cam carried by the aforementioned operating shaft.

The sub-units mentioned above consist of limited groups (having one hundred selectable ele- 40 ments in the instant embodiment) which are disposed perpendicularly with respect to said connector bars, and each has a number of selector bars which are set through the medium of a plurality of links which articulate the sub-unit selector bars with the connector bars. A-sub-unit spreader cam is supported beneath the alignment of selector bars andfunctions to restore cyclically any one of them following its selection. The several spreader cams are operated together from a common operating shaft which extendsvparallelly of. the aforementioned connector bars and is driven by the main operating shaft.

Each sub-unit supports a limited number of individually selectable elements which are pivot- 5 ally suspended in a criss-cross alignment and position of the code bars favors a particular selectable element, it is permitted to move into socalled selected position following the recession of its spreader cam at which time a lug appendaged thereof closes a contact pair establishing or preparing an individual circuit over which price signals are routed thereafter.

For a more comprehensive understanding of the present invention, reference may be had to 20 I the. more detailed description following hereinafter and to the accompanying drawings wherein like reference characters represent similar parts throughout and wherein;

Fig. 4 is a fragmentary plan view of certain of the operating elements featured in the selector mechanism of- Fig. 1, and;

Fig. 5 is a perspective view of a portion of the selector mechanism featuring the staggered ar- 40 rangement of the magnets.

The embodiment featured herein is contemplated for use with a receiving distributor having the characteristics featured in the above referred to application. Particularly is it adapted 45 to the use of five unit start-stop permutation code signals wherein three stock selecting signals are employed giving a total of fifteen principal component selecting elements. In addition to the fifteen selector bars, two additional bars are 50 provided whose selection represents a secondary preference such as is sometimes termed first preferred, "second preferred, fcommon, etc.,

so that in accordance with a given stock designation, various subordinate classifications may be independently distinguishable one from another. Preferably the signals are momentarily stored in a group of storage relays from which they are transferred to the stock selector magnets I88. 5 An arrangement illustrating this is disclosed in the aforementioned parent application, Serial No. 58,340.

As indicated in the accompanying drawings, the stock selector unit includes a set of compactly arranged selector banks or sub-units I18 which are-mounted on a base casting I18. The number of these sub-units which may be employed at any particular stationds dependent, of course, upon the number of stocks which it may be desired to serve. In accordance with the operating principles of the unit about to be described, it has been found that five hundred or more'selections may be conveniently accommodated by the arrangement of the tiers I18, each one of which 20 contains one hundred individually selectable elements I11. In other words, an infinite number of tiers may be arranged parallelly, as shown, consistent with the inherent mechanical limitations of the arrangement. It has been definitely established by experiment that at least five such tiers may be associated within a single assembly and driven from a common source as will be presently explained.

Magnets I68, seventeen in number, are staggered as indicated in Figs. 1, 4 and 5, so as to permit their close grouping about the region of the transfer elements and pivot shaft I58. The energization of each magnet I88 causes the attraction of its armature I18 and moves setting as needle I8I inwardly so as to engage and shift its corresponding selector lever I82. It will be particularly noted that alternate ones of the selector levers I82 are similarly shaped and that they differ from the intervening ones in slight detail,

40 viz; the location of the contacting surface I83. This feature is designed to conform with the staggered arrangement of the magnets I88. In opposition to the influence of magnets I88, each setting lever or selector lever I82 is instantly 5 returned to normal position by a spring I48 upon the deenergization of its associated magnet I68. Accordingly, the energized or deenergized condition of each magnet I88 is manifest upon its associated selector lever I82 during the signal 50 relaying period resulting in the disposition of each selector lever either as indicated in solid or as in dotted lines in Fig. 4.

A set of T-shaped transfer levers I84 comprising one for each of the selector levers I82 is carried upon a common shaft I85, which in turn is supported at its ends by a bail lever I81 pivoted on the trunnion screws I88. A spring I88 is connected to an ear which extends from bail lever I 81 urging the latter in a clockwise direction, as

viewed in Fig. 4 about its'pivots I88 and causing the follower roller I18 thereof to engage the periphery of a cam I88 on shaft I18. Upon the rotation of shaft I18, cam I88 causes rocker bail I81 to be reciprocated about itspivots I88 so that 5 the assembly of transfer levers I84, which are pivotally carried upon shaft I85, are thrust against the selector levers I82. When this happens, one or another of the transfer lever lugs I88 or I8I coming into engagement with its re lated transfer lever I82 at either of its shouldered extremities I88, causes said transfer lever I84 to yield and rotate in a related direction and in accordance with this, the transfer lever disc I88 is moved in a corresponding direction. Since the discs I maintain an articulate relationship with the sockets I82, the transverse connecting bars I88 are correspondingly shifted, and the latter, through the disc and socket connections I84 and I88, impart a' shift operation to each of the oscillatory levers I88.

The opposite ends of each of the reciprocable levers I88 are rounded and thereat engage a cammed end surface of a selector bar I81 whose edges are studded with regularly occurring lugs and intervening equally spaced notches. All of 10 the selector bars I81 of a tier I18 are aligned vertically and constitute a parallel stack. Each bar is provided with a spring I88 which tendsto maintain said bar in its right-hand position as viewed in Fig. 4. This condition is permitted only 1 during the time inwhich reciprocating lever I88 is in its clockwise extremity as indicated in dotted outline, Fig. 4, but when in its counterclockwise position, as indicated in solid outline, the round extremity of reciprocating lever I88 urges against 20 an extending cam surface on the end of selector bar I81 shifting the latter to the left and in opposition to its individual return spring I88. In this manner, the condition of the seventeen selector bars I88 is always impressed upon each 25 of the stacks of selector bars I81 establishing a uniform selecting condition throughout the entire system.

As has been said, for each arrangement of the seventeen selector bars, an individual selectable 80 element is conditioned to the exclusion of all of the other selectable elements. In a system employing seventeen selector bars, the total number of selectable elements which may be thus served is equivalent to two to the seventeenth 85 power or 131,872. For each cycle of operation or permutative selection, a certain disposition of the seventeen bars I88 is made, causing an alignment of notches somewhere in one of the tiers I18 among the selector bars I81 which will 0 correspond to the individual arrangement of lugs I88 upon one of the selectable elements I11, permitting the latter to be moved into its selected position which, as will be described later, will be I moved inwardly under the influence of its spring 4,5 "I. For each of an oppositely disposed pair of selectable elements I11, a single interconnecting spring 28I is provided, while a pair of transverse rods 28I serve as pivots about which the two alignments of bars are suspended in grooves 288 go between end frames 288 and 2 I8. A spreader cam 282 is located beneath the stock of selector bars I81 and between the lower extremities 283 of the selectable elements I11. The several spreader cams 282 are indicated as being integral with the 56 transverse shafts 288 which are suitably journaled in the end frames 288 and 2| 8, and which are provided with the driven gears 228. The normal position of each spreader cam 28! is at 90 from that indicated in Fig. 3, at which time 80 the selectable elements I11 are cammed outwardly a suflicient distance to permit selector bars I81 to be shifted clear of the lugs I88.

When in the position indicated in Fig. 3, however, cam 282 permits the selectable elements I11 85 to come into engagement with the selector bars I81, and when this occurs the lugs I88 may avoid the lugs of selector bars I81, in accordance with the particular disposition and selectable element I11 will be permitted to rock about its shaft BI 70 until the hook portion 284 thereof is enabled to close the contact pair 285288. The closure of this contact pair prepares an individual routing circuit in a manner more clearly described in the parent application permitting the recordal8 tion of price or so-called answer signals on a selected indicator.

Following the recording operation, cam 282 resumes its original position whence its cam surfaces 201 reengage the curved projection 283 of the selected element while also spreading the other elements into their distended positions.

It should be noted that selectable elements I11 thereof that are oppositely disposed in transverse alignments are nevertheless of similar shape and configuration excepting the disposition of their code lugs. For this reason any selectable element I11 is capable of being inserted into position on any tier I16 and on either side thereof. The notches upon the selector bars I91 are of regular or equally spaced occurrence, while the lugs I99 of the selectable elements I11 are bent some rightwardly and others leftwardly in an individual manner that characterizes each element. Accordingly, the construction permits of unrestricted interchangeability of the elements I11 because the location of any one of them is not dependent upon any predetermined features of the unit.

The transverse shafts 288, Figs. 1 and 2, are driven from a common operating shaft 209, which is located parallelly with respect to and just below the connecting bars I83. Shaft 209 is driven by a short drive shaft 2I I which in turn is geared at 225 to the vertically presented main operating shaft I18. The latter is driven through a toothed driving clutch 222, the driving element 223 of which is continuously rotatable with the driven gear 2I3, and the latter, in turn, is actuated by a worm gear 2| 4 which is carried upon the end of the intermediate drive shaft 2I5. A motor 2I6 having a suitable speed regulator 230, drives intermediate shaft 2I5 through gear pair 2I1. A speed regulator adaptable to this purposeis shown and described in U. S. Patent No. 1,306,072 issued to B. F. Merritt. Shaft I18, which has been referred to as the vertical operating shaft, carries the rocking bail operating cam I 88, which functions to reciprocate the transfer bail I81, as aforedescribed, and to thereby execute a signal transfer of all of the selective conditions established in the several selector levers I82 to their corresponding connecting bars I93. Another cam 2I8 also on shaft I18, Fig. 4, cooperates with a detent jockey 2I8 and acts to maintain shaft I18 in a dormant or quiescent condition during the clutch disengagement period by withholding the teeth of driven member Hi from clashing with those of driving member 223. This jockey 2 I9 resists counterclockwise rotation of the driven assembly which includes shaft I18, such rotation being mildly urged by the spring 224 in forcing member 22I downwardly and through the beveled lug 228 against a similar bevel on the cooperating surface of armature 228, Fig. 1.- Upon the release of armature 228, the movement of member 22I is permitted in a vertical direction.

As stated before, shaft I18 is driven by intermediate shaft 2 l5 and has secured to it the driving gear 225 which actuates drive shaft 2| I. At its upper extremity shaft I18 carries the transfer bail operating cam I88 and the anti-gnash cam 2I8 as well as the longitudinally slidable driven portion 22I of clutch 222. When motion is imparted to the shaft I18 through clutch 222, the entire assembly including the cams I 86 and 2I8 and the gear 225 is rotated together imparting movement to shafts 288, 2| I and spreader cam shaft 288.

The disengagement of clutch 222 is subjected to 232 clears transverse rods 23I.

' ting the floating portion 22l to come into engage- .ment with the driving teeth of clutch element 223.

Each stock or commodity selecting element having a particular code combination may be identified by suitable surface markings or by recognizing and distinguishing between the several of its lugs I I9 which corresponds to the three principal selecting signals. To remove any element 30 I11 from its position, itis but necessary to disconnect it from spring 2M after which it may be pulled directly upward and inwardly until its claw Thereafter the element may be slid out of its slot 233 in the frame and any other element replaced in its stead. This interchangeability of elements I11 permits of a practice of quickly and easily delegating a given position in an arrangement of stock indicators to any desired stock. F
